Seuratizer - (added 12/25/13, Merry Christmas!) - this is an offshoot of the spraypaint brush. It's chock-full of controllers, but mainly it dances around the selected hue by a few degrees while changing value and scatter distance from pressure. Was trying to make a brush that would emulate pointillism. It works well as a image-based color filter and also for leaves and such.

Here ya go. It's an offshoot of the shadow brush. Pressure will basically change the shadow contrast as it will spread the light and dark apart. Very light pressure will just do alternating light/dark in a line. Just add the random signal to the rotation controller and use the solid square shape for the fuzzy effect shown in the picture. With random rotation on, try the empty square for another weird effect not shown.

Edit - forgot to mention: increasing the size (try 50px) is an easy way of smoothing the shadow (less jagged).

Can you please help me to know, what are the names of the tools that are used in Photoshop for giving special effects to the pic.. like those you have given spray , brush etc.. I am not that much aware about them I am just a beginner and looking some sort of idea to how to use such tools. But I am not sure which I have to use for which purpose...

Photoshop was only used to copy and paste images together for the Seuratizer sample - everything else was done in BlackInk. The spraypaint and seuratizer samples use image-based color: download the attached brush; install it into the correct directory; open BlackInk and select the brush; choose image-based color (mona lisa); click the folder that pops up below to load an image; paint over the image. To do a drip effect: select the simple round brush; hold shift (will straighten stroke path); paint downward with decreasing pressure (decreases in size). The background of the frog image is just scattered empty circles - can't remember the specific brush I used there, but most will work with a few adjustments. It may help to know that these brushes were intended for use with a pen and tablet - it may be difficult to achieve the same results with a mouse. Hope this helped - let me know if there's anything else.
